By using a longitudinal approach the current study examined the impact of (a) positive self- presentation, (b) number of friends, and (c) the initiation of online relationships on Facebook on adolescents’ self-esteem and their initiation of offline relationships, as Edited by: well as the mediating role of positive feedback.

We applied two conceptual schemes to dissect the evidence in peer-reviewed literature so far, as a basis for better understanding and enabling ‘building back better’. Reported positive impacts of the lockdown ‘anthropause’ on environmental conditions were likely only short-term, while progress towards sustainable development goals was more consistently set back especially for social aspects such as livelihood, employment, and income. The loss of interconnectedness, driving loss of assets, followed a ‘collapse’ cascade that included urban-to-rural migration due to loss of urban jobs, and illegal exploitation of forests and wildlife. Agricultural activities geared to international trade were generally disrupted, while more local markets flourished. Improved understanding of these pathways is needed for synergy between the emerging adaptive, mitigative, transformative, and reimaginative responses. Dominant efficiency-seeking strategies that increase fragility will have to be re-evaluated to be better prepared for further pandemics, that current Human–Nature interactions Citation: Duguma, L.A.; are likely to trigger. -

Humans are encroaching on animal environments, raising chances for pathogens to adapt from animals to people. An increasing share of the planet lives in megacities, heightening the likelihood of person-to-person transmission of pathogens. The movement of people and microbes around the globe is more efficient than ever.

Friendship Paradox in Growth Networks: Analytical and Empirical Analysis
Sidorov et al. Appl Netw Sci (2021) 6:51 https://doi.org/10.1007/s41109-021-00391-6 Applied Network Science RESEARCH Open Access Friendship paradox in growth networks: analytical and empirical analysis Sergei P. Sidorov* , Sergei V. Mironov and Alexey A. Grigoriev *Correspondence: [email protected] Abstract Saratov State University, Many empirical studies have shown that in social, citation, collaboration, and other Saratov, Russia 410012 types of networks in real world, the degree of almost every node is less than the aver- age degree of its neighbors. This imbalance is well known in sociology as the friendship paradox and states that your friends are more popular than you on average. If we intro- duce a value equal to the ratio of the average degree of the neighbors for a certain node to the degree of this node (which is called the ‘friendship index’, FI), then the FI value of more than 1 for most nodes indicates the presence of the friendship paradox in the network. In this paper, we study the behavior of the FI over time for networks generated by growth network models. We will focus our analysis on two models based on the use of the preferential attachment mechanism: the Barabási–Albert model and the triadic closure model. Using the mean-feld approach, we obtain diferential equa- tions describing the dynamics of changes in the FI over time, and accordingly, after obtaining their solutions, we fnd the expected values of this index over iterations. The results show that the values of FI are decreasing over time for all nodes in both models. -

Biol. Lett. 16: 20200641. The COVID-19 pandemic has altered human behaviour in profound ways, http://dx.doi.org/10.1098/rsbl.2020.0641 prompting some to question whether the associated economic and social impacts might outweigh disease impacts. This fits into a burgeoning ecologi- cal paradigm suggesting that for both predator–prey and parasite–host interactions, non-consumptive effects (avoidance) can be orders of magni- Received: 2 September 2020 tude stronger than consumptive effects (sickness and death). Just as Accepted: 28 October 2020 avoidance of predators and parasites imposes substantial costs on prey and hosts, altered behaviour to reduce the transmission of COVID-19 has impacted human fitness and wellbeing. But the effects of infectious disease avoidance do not stop there; non-consumptive effects of predators and parasites often trigger cascading indirect effects in natural systems. Similarly, Subject Areas: shifts in human behaviour due to COVID-19 have triggered myriad indirect behaviour, ecology, environmental science, effects on species and the environment, which can be positive, negative or health and disease and epidemiology neutral. We urge researchers to recognize that the environmental impacts associated with lockdowns are indirect effects of the virus. -
Network Interventions Based on Inversity: Leveraging the Friendship Paradox in Unknown Network Structures
Network Interventions Based on Inversity: Leveraging the Friendship Paradox in Unknown Network Structures Vineet Kumar,1∗ David Krackhardt,2 Scott Feld3 1 Yale School of Management, Yale University. 2Heinz School of Public Policy and Management, Carnegie Mellon University 3 Department of Sociology, College of Liberal Arts, Purdue University. ∗To whom correspondence should be addressed; E-mail: [email protected] Network intervention problems benefit from selecting a more connected node, which is more likely to result in stronger indirect effects. However, in many network contexts, the structure of the network is unknown. We derive and examine the mathematical properties of two distinct “informationally light” strategies, a global strategy and local strategy, that yield higher degree nodes in virtually any network structure. These strategies are based on the friend- ship paradox: “your friends have more friends that you do.” We further iden- tify a novel network property called Inversity, which connects the fundamental parameters of these two strategies. We prove that the sign of Inversity for any given network determines which of the two strategies will be most effective in that network. We assess the performance of these strategies across a wide range of generative network models and real networks, and we show how to leverage network structure through these strategies even when the network structure is unknown. 1 Network-based interventions are of crucial importance in any setting where an individual’s choice or action has a multiplier impact on others, with a wide range of applications. Consider the following network intervention problems: (a) A new infectious disease is spreading through a large population. -
Framework on Accumulating Evidence Across Outbreaks

Impact decision-making of caregivers and policy makers . Jeopardize the conduct of future confirmatory trials 7 Recommended approach We advocate for the use of a “master protocol” to preserve data confidentiality and trial integrity until the scientific aims have been reliably addressed Master protocol = conventional clinical trial designed to extend across multiple sites and outbreaks Trial results are released only following the advice of an independent data monitoring committee (e.g. stop for efficacy, futility, reached target # of endpoints) and not due to lack of recruitment 8 Practical considerations Multi-site trial in high-risk areas with opportunity to add sites -

Published by AuthorHouse 10/15/2020 This story is for my grandson, Rohan. Like most children, the COVID-19 pandemic limited his access to traditional teaching. But learning never needs to stop. It has no artificial boundaries. Big Rat, the main character in this story, is a curious teacher. His insights about the pandemic give a viewpoint that can be both comforting and inspirational for children during anxious times. Big Rat gives hope for the future with many timeless messages. This is a fictional child’s book based on real animals. It takes place in Hawaii in 2020, during the COVID-19 pandemic. The protagonist is a character called Big Rat. -
